63644098 ÷ 28 
Let's see how many times 28 fits into 63644098.

Going ahead to step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 28

Step 2:
28 can be fit into 63 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 56 from 63 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 28

Advancing to step 3:
28 can be fit into 76 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 56 from 76 to get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 28

Let's proceed to step 4:
If we divide 204 by 28, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 227.0
If we take 196 away from 204, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 28

Going ahead to step 5:
If we divide 84 by 28, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 2273.0
If we take 84 away from 84, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 28

On to step 6:
The number 28 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22730.0
If we take 0 away from 0, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 28

Going ahead to step 7:
The number 28 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 227300.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 28

On to step 8:
98 divided by 28 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 2273003.0
Deduct 84 from 98 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
When dividing 140 by 28, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2273003.5
If we take 140 away from 140, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2273003.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 28, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2273003.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2273003.5 and a remainder of 0.0.
